What it is
Solves run on your machine. Cards are not uploaded. It is not a place to play for money, and the terms say the software makes no promise of winnings.
The desktop app is version 0.1.0, released 6 October 2026. It runs on Windows 10 and 11, 64-bit or 32-bit. This site does not offer a macOS installer or a mobile app. The installers are on the download page. Those builds are not digitally signed.
How to reach the operator
Support mail is support@ofclab.app. The help center says replies are within one business day. Account data is described in the privacy policy. Payments go through Stripe. Sign-in is Supabase, the same account the desktop app uses.
How results are checked
Street and Taiwanese EV are high accuracy. 2-7 Fantasyland is an exact optimum. High-middle Fantasyland is the best board found. The Rust engines match the JavaScript engines on fixed hands, with EV within 1e-6. How the numbers work.
